Product Description

YQ7 Multi-parameter Detection Alarm Instrument

The YQ7 multi-parameter detection alarm instrument simultaneously and continuously monitors 7 critical parameters including CH4, O2, CO, CO2, H2S, temperature (°C), and wind speed (m/s). This advanced detector triggers immediate audible and visual alarms when parameter levels exceed or fall below preset safety thresholds, enabling timely safety measures to protect life and property.

Utilizing an 8-bit microcontroller and high-precision detection components, the YQ7 delivers exceptional sensitivity and rapid response times. The 3-inch color LCD provides clear, reliable data display. Certified by national authorities, this instrument is suitable for all personnel including technicians, operators, and management in industrial environments.

Key Features

Simultaneous detection of 7 parameters: CH4, O2, CO, CO2, H2S, °C, and m/s
User-configurable alarm points for customized safety thresholds
Secondary sound and light alarm functionality
Replaceable modular sensors for easy maintenance
Comprehensive monitoring for mine gas and environmental parameters
One-click zero calibration and charging zero calibration
